Allegro 4 (a game library used by EOF) is not compatible with certain EAX emulation features some sound cards use. This problem mostly seems to be associated with Xonar sound cards, and disabling the relevant feature (it may be called something like "GX mode") could fix it. Otherwise, generally whatever sound device is the default sound device at the time EOF launches is the one that will play EOF's sound during that session.

*Fixed a bug with Feedback import where mid-beat tempo changes would cause a text event to import onto the wrong beat marker.*Improved the "Imports drop mid beat tempos" handling to only delete the first of consecutive beats inserted due to consecutive mid-beat tempo changes.*Improved MIDI import's handling of charts with lyrics incorrectly defined as text events, by not importing those events as text events in addition to importing them as lyrics.*Changed the metronome so that by default, a lower pitched tick sound is used for beats that have a time signature in effect and aren't the first beat in a measure. This can be disabled by unchecking the "Use multi-pitch metronome" checkbox in "Song>Audio cues".*Changed the slider mechanism to be usable in the keys track, for use in Clone Hero.*Fixed some bugs in "Beat>Reset offset to zero".*Added handling for the close window control.*Returned the CTRL+SHIFT+R shortcut to "Resnap to this grid" and assigned ALT+R to "Resnap auto".*Improved the error handling for when a custom window size couldn't be set.*Added CTRL+ALT+Y/G/B shortcuts to toggle cymbal+tom status for selected cymbals in the Phase Shift drum track.*Improved Guitar Pro import of drum tracks to be able to apply cymbal+tom status to notes imported into the Phase Shift drum track if they are defined to have both a tom and a cymbal at the same place. If the destination of the import includes the normal drum track, a message is displayed warning that cymbal+tom status is only applicable for the Phase Shift drum track.*Improved file imports so that if a file named drums.ogg, rhythm.ogg or song.ogg is selected as the chart audio, that file is copied to the project folder if necessary and used with its original file name instead of being renamed to guitar.ogg.
